What is Panda update in SEO?

Google's Panda Update is a search filter introduced in February 2011 meant to stop sites with poor quality content from working their way into Google's top search results. Panda is updated from time-to-time. When this happens, sites previously hit may escape, if they've made the right changes.

The “Panda update” was an adjustment of the Google Search algorithm, introduced in 2011. The Panda update, alongside the Penguin update, is one of the most important Google updates, as its effect on the rankings of websites was dramatic. The primary goal of the Panda update was the improvement of search results by filtering out substandard sites.
